Assuming the wrong programme areas in your cost plan or cost estimate is a fatal mistake, and can blow project budgets for construction projects
Here is a tip for your RICS APC “Quantification and Costing of Construction Works” Core Competency...
Before you start working on a Cost Plan or a Cost Estimate, you should do the following:
1. Identify the standard method of area measurment that you will be using for your area and volume calculations (i.e. RICS Code of Measuring Practice, BOMA Floor Measurment Standards, etc. )
2. Agree and define with the project team the area type that you will be measuring (Gross External Area, Gross Internal Area, Net Internal Area, etc.)
3. Measure the programme areas, and provide the project team with a copy of your ‘marked-up’ drawings and take-off.
4. Tabulate your areas, and compare to the Architect and Client’s areas - if available.
5. Reconcile any deltas in areas with the Architect and Client. The delta in areas should not be more than 5%
6. Agree with the project team on the final programme area, then document
Once all the above is done, then you can proceed with confidence to the next step of your cost planning or cost estimating
